l MERCHANDISE-ENVELOP.

To all whom it may concern Be it known that I, WILLARD E. SWIFT, a citizen of the United States, residing at WVorcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Merchandise-Envelops,of which the following, taken in connection with the accompany ing drawings, is a specification.

My invention relates to that class of merchandise envelops in which the closing flap of the envelop, when in its closed position, is secured to the body of the envelop by means of a metallic fastener having one or more bendable tongues adapted to be inserted through one or more openings in the closing flap and to be bent over the outside of the closing flap, and it consists in providing novel means for securing the metallic fastener to the body of the envelop, whereby the bendable tongues are securely and rigidly maintained in proper position to be passed through the opening provided therefor in the closing flap.

The above and other objects are attained by the construction and arrangement of parts as hereinafter set forth and illustrated in the accompanying drawings,-in which- Figure 1 represents in plan view one end of a merchandise envelop having a metallic fastener embodying my invention, the closing flap being shown in its open position. Fig. 2 represents the same view at Fig. 1, but with the closing flap shown in closed position and secured to the body of the envelop by a metallic fastener embodying my invention. Fig. 3 is a plan view of the inner side of a portion of the body of the envelop, illustrating the method of securing the metallic fastener thereto. Fig. & is a plan view of my improved metallic fastener ready for attachment to the body of an envelop. Fig.

5 is a side or edge View of the fastener. Fig. 6 is an end view. Figs. 7, 8 and 9 are plan side and end views, respectively, of my improved metallic fastener, showing a modification in the form of attaching the prongs, and Fig. 10 is a sectional view through the body portion of an envelop, showing the method of clenching the prongs of the fastener, the section being shown on the line 10-10, Fig. 3.

Like reference characters are used to designate like parts in the different figures.

Referring to the drawings, 1 denotes a Specification of Letterslfatent. Patented June 29, 1915. 5 Application filed October 9, 1914. Serial no. 865,832. a 6

portion of a merchandise envelophaving a closing flap 2. and a metallic fastener 3 embodying my present invention. Themetallic fastener 3. is provided with a pair of bendable tongues 4 and 5 on opposite sides of its central portion, which lieflat against the envelop, when the fastener is applied there-1 to,-but are capable of being bent at right angles tothe envelop so as to bring the tongues 1 and 5 parallel to each other and enable their tips to be inserted through suitable openings 6, 6 in the closing flap when the latter is folded over in its closed posi- I tion, as shown in Fig. 2. The openings 6, 6 are preferably reinforced by attaching an adhesive strip 7, of firm paper or cloth, to the inner side ofthe closing flap. After the insertion of the tongues 4 and 5 through the openings 6, 6, the tongues are bent outwardly against the outer side of the closing flap, as shown in Fig. 2, to securely retain the flap in its closed position.

My improved metallic fastener is formed from a thin bendable sheet metal plate 8, preferably having rounded ends 9, 9 to facilitate their insertion through the openings of the closing flap. On opposite sides of the center of the plate 8, and slightly spaced apart, I cut the converging slits 10, thereby forming a pair of triangular prongs 11, 11 which are bent downwardly at their bases 12 into the position shown in Fig. 5, leaving envelop, as shown at 14, 14:, Fig. 3. In this position the plate 8 lies flat against the outside of the envelop as represented in Fig. 1. At the bases 12 of the triangular openings 13, the plate 8 becomes weakened, which permits the ends of the plate to be bent upwardly at right angles to the surface of the envelop, forming bendable tongues 15, 15, in the position shown at 15, 15 Fig. 5. The bendable tongues are then inserted through the openings 6, 6 in the sealing flap and are bent down upon the outer side of the sealing flap into the position shown in Fig. 2.

In Figs. 7, 8 and 9 I have shown a slight modification in the form of the attaching prongs which, instead of being made tri-' creases the bearing surfaoe of theprongs against the bodyportion of the envelop,

The fasteners may be stamped'frointhin v p (through the body portion of the envelop sheet metal plate, or they may be conveniently and cheaply formed from-a rnetallicribbon of the proper Width, Which Will only require that the attaching. prongs be formed at proper distances apart and. the ribbon severed toform individual fa'stenersi- I claim,

A merchandise envelop having-an opening in its closing flap,,and provided with a metaliic; fastener comprising a sheet metal plate having apair of pointed prongs struck oiit from the body portion thereof onloppo Gopiesof this patent m'a'y be obtained for site sides of its center by means of pairs of intersecting slits converging toward the ends of said, plate, said prongs being inserted andclenohed upon the inside of the same,

with the portions of said plate beyond the base portions of saidrprongs adapted to lie parallel and in substantial juxtaposition when bent upwardly for insertion through the opening of said closing flap.
